ADVANCED SEMICONDUCTOR ENGINEERING, INC. REPORTS CONSOLIDATED
YEAR 2003 THIRD-QUARTER FINANCIAL RESULTS

Taipei, Taiwan, R.O.C., October 30th, 2003 – Advanced Semiconductor Engineering, Inc. (TAIEX: 2311, NYSE: ASX) (“We”, ASE”, or the “Company”), one of the world’s largest independent providers of semiconductor packaging and testing services, today reported unaudited consolidated net revenues¹ of NT$14,525 million for the third quarter of 2003 (3Q03), up 22% from the year ago period and up 14% sequentially. Net income for the quarter totaled NT$583 million, representing earnings per share of NT$0.16, or US$0.024 per ADS.

For the first nine months of 2003, the Company’s revenues were NT$38,882 million, up 19% compared to the same period of 2003. Net income was NT$595 million, compared to NT$158 million in the first nine months of 2002. EPS was NT$0.17, or US$0.025 per ADS.

“Our consolidated revenues reached NT$14.5 billion for the third quarter of 2003, which is record quarterly revenues for ASE Group,” commented Mr. Jason Chang, Chairman of ASE. “We have witnessed significant increase in chip volumes in our operations from customers in all three end markets, namely consumer, computer and communication. The strongest growth came from our customers who require leading edge capacity to support their new products, especially in the communication and computer sectors.”

“As a result of our investment in research and development, as well as in leading edge packaging and testing capacity, we are now in a very favorable position to become a true leader in the industry. We have aligned and timed our capital expenditures with industry demand. Although we have pursued an aggressive expansion plan in the last few quarters, we are still able to increase the overall utilization rate every quarter and consequently improve our margin. The pricing environment remains stable, mainly due to limited supply of leading edge backend capacity.”

“In addition to ramping up packaging and testing volumes, we also made significant improvement in our substrate operations. Revenues from our substrate operations grew more than 100% versus the same quarter in 2002, and our substrate division also began to contribute profit to the group. The importance of internal substrate supply cannot be over emphasized. The demand generated from accelerated migration from traditional leaded-base packages to laminate-based technology far exceed existing supply. Going forward, the growth and profitability of any packaging company shall be contingent upon stable supply of substrate. In view of increasing demand for substrate, on October 28, 2003, we formed a joint venture with Compeq, a leader in PCB and substrate manufacturing. Through this joint venture, ASE will have access to Compeq’s

existing substrate capacity, whereas Compeq will be able to leverage on ASE’s existing customer base. We see great synergy between the two companies.”

“Meanwhile, in our constant effort to streamline our operations, we also announced the merger of ASE (Chung-li) Inc. and ASE Material Inc. with ASE. Through this merger, we intend to further consolidate our group resources to fully capitalize on our economies of scale and, at the same time, simplify our organizational structure to provide even better transparency to our investors and customers.”

BUSINESS REVIEW

Packaging Services

• Revenues generated from our packaging operations were NT$11,420 million during the quarter, up 24% year-over-year and up 14% sequentially.

• Revenues from BGA and other substrate-based packages (including flip chip BGA) comprised 54% of total packaging revenues during the quarter, compared with 53% in 3Q02 and 50% in the previous quarter. The sequential increase in BGA revenues was due primarily to the higher volume of certain communication and computer devices that predominantly use substrate-based packages.
